Computer systems may use a multi-tier software architecture, which may include, for example, a user interface tier, a middleware tier, and a backend tier. In developing software for such architectures there may be multiple development teams working on features which require cooperation between software in different tiers. Furthermore, such development teams may operate in different countries and time zones. Coding performed for higher level tiers depends on capabilities of lower tiers being exposed. Changes made to capabilities of lower tiers may cause code of higher tiers to fail and/or require additional development to be performed. A product may not be released until the code of all of the tiers interacts successfully.
